View profileOmnicom-owned integrated agency combining PR, creative, digital, social and media for travel, hospitality and consumer brands.

The Zimmerman Agency is a Tallahassee-based integrated marketing and public relations firm founded in 1987. Since joining Omnicom in 2004, it has combined an entrepreneurial agency structure with access to a larger media, technology and global-resource network.
Zimmerman is positioned between an independent integrated agency and a holding-company resource platform. Its strongest public work sits where brand strategy, creative, media and public relations must operate together, particularly for travel and hospitality businesses seeking measurable demand.
The agency’s six core disciplines are strategy, creative, public relations, digital, social and media. Its proprietary Momentum Planning approach connects audience insight and brand ambition to campaign ideas, while in-house production, analytics and media buying support execution.
Travel and hospitality are especially visible in the public portfolio. Work for The Leading Hotels of the World combined creative, content and media, while the broader client record spans consumer, retail, destination and lifestyle assignments.
A single Tallahassee headquarters is supported by Omnicom resources and partner capabilities. The model can therefore handle national or international programs without presenting a large proprietary office network under the Zimmerman name.
A human editor reviewed Zimmerman’s current site and a client-hosted procurement proposal. Both sources present a consistent record of long tenure, Omnicom ownership and integrated delivery; no review-platform material was used.
A hospitality case reports more than $2 million in attributable revenue, over 12,000 booking-engine interactions and 2.6 million social impressions. A separate client-hosted proposal corroborates the agency’s Omnicom ownership and broad service platform.
Technology signals include a social command center, audience research, campaign analytics, CRM, site development, search optimization and access to Omnicom tools. Public descriptions do not identify a standalone proprietary software product beyond the Momentum Planning methodology.
The practical differentiator is full integration under one agency team, backed by Omnicom media scale. That combination suits clients wanting public relations to work alongside paid media, creative production and conversion-oriented digital activity.
Compared with PR-only firms, Zimmerman offers substantially more media, creative and digital infrastructure. Compared with large network agencies, it presents a smaller operating center with founder continuity, while still drawing on holding-company resources.
